Description

[Detailed description of the invention] This invention relates to a counterweight for an elevator that is filled with concrete or the like and integrated.

First, a conventional elevator counterweight will be explained with reference to FIG.

In the figure, 1 indicates the framework of the upper frame 1a hanging frame 1b lower frame 1C and hanging frame 1b
A box-shaped body 1 composed of side plates 1d covering both sides of a lower frame 1C
A box-shaped body 1e is filled with a filling material 2 such as concrete, and a weight adjustment sub-weight 3 is placed on top of the box-shaped body 1e. The robot is guided by guide rails 6 and moves up and down within a hoistway (not shown).

That is, the framework of the counterweight 1 is carried into the hoistway, and the box-shaped body 1e is filled with the filling material 2 from above and installed.

Then, in order to sufficiently fill the box-shaped body 1e with the filler 2, the filler 2 was gradually inserted while being poked with a rod or the like.

However, in the case of a deep box-shaped body 1e, a long driving rod is required, which has the problem that the operation of the upper frame 1a is obstructed, resulting in incomplete filling of the filler material 2.

This invention solves the above-mentioned drawbacks and aims to provide a counterweight for an elevator that allows the box-shaped body to be easily filled with filler material.

An embodiment of this invention will be described below with reference to FIG.

In the figure, the same symbols as in FIG. 1 indicate corresponding parts, and 1e indicates the side frame 1.
d It is a box-shaped body formed by a lower frame 1C, and an opening 1f for filling the filler 2 is provided on the upper surface, and 7 is made of an upper layer and is placed directly above the box-shaped body 1e. Directly above member 1a,
It is a frame-shaped body made up of hanging frames 1b.

Reference numeral 8 denotes an engager arranged at the upper edge of the box-like body 1e and engages with the guide rail 6; 9, the lower part of the frame-like body 7; the upper part of the box-like body 1e; A bolt 10 for fastening the three members 10 and 18 is a fastener consisting of a bolt that removably fastens the directly above member 1a to the frame body 7.

That is, only the box-like body 1e is erected between the guide rails 6 by the engaging elements 9 and the guide shoes 5, and the filler 2 is filled therein.

At this time, since the frame-shaped body 7 is not attached to the box-shaped body 1e, it is possible to sufficiently fill the filler 2 with a rod or the like.

Therefore, the installation work of the counterweight 1 can be improved.

Then, the frame-like body 7 is attached, and the installation of the counterweight 1 is completed.

In this way, the filler 2 can be implanted with at least the directly above member 1a not attached, so that the counterweight 1 having the required weight can be easily obtained.

As explained above, in this invention, the member or frame-like body placed directly above the box-like body having an opening for filling the filler material on the top surface is removably fastened, so that the filler material can be easily filled. To realize a counterweight for an elevator in which a box-shaped body having a required weight can be easily obtained and has good installation workability.
